' DEVICE FOR TRANSFERRING DOUGH;

Specification of Letters Patent.

Patented Mar. 31, 1914.

Application filed October 17, 1912. Serial No. 726,315.

To all whom it may concern Be it known that 1, CHARLES Fnnrnornn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented. Improvements in Devices for Transferring Dough, of which the following is a specification.

One object of my invention is to provide a relatively simple and conveniently operative device whereby a number of bod ies of dough may be quickly and simultaneously transferred from a box or other container in which they have been allowed to rise, on to a peel preparatory to placing them in an oven. These and other advantageous ends are secured as herewith set forth, reference being to the accompanying drawings in which,

Figure 1 is a front elevation of a machine constructed according to my invention, Fig. 2 is a side elevation of one end of the machine shown in Fig. 1. Fig. 3 is a frag-- -mentary perspective view of the jaws formmachine, and Fig. 4: is a of a portlon of one of the machlne 1s employed.

ing part of the perspective view containers which my to invert.

In the above drawings, 1, 1 are a pair of standards each of which is provided with a bearing 2 for the reception of a short shaft 3 projecting on both sides thereof, each shaft having on that end which'is directed toward the other shaft, a jaw structure 4:, while on its opposite end there is fixed a segmental gear 6, which meshes with a toothed segment 7 carried on a pivot or spindle 8. This latter is supported by a portion of the standard 1, and there is a handle 9 formed integral with or attached to the segment 7 for turning the same so as to cause revolution of the gear or segment 6 and the shaft 3.

Each of the jaw structures 1 consists of a fixed laterally prolonged jaw 10, having an extension 11 in the form of a guide bar proj ecting in a line at right angles to the line of the two shafts 3, Each of these bars 11 is p ovided with a ratchet formed in the pres ent instance by a toothed rack 12, and on its outer end has a head 13 held in position by any suitable means, there being an annular recess in its inner face for the reception of a portion of a spring 1%, coiled around said bar. Slidably mounted on each bar 11 is a second jaw 15 designed to cooperate with the jaw 10, and as best shown in Fig.

3, laterally extended like the jaw 10. The adjacent faces of the two jaws are preferably toothed or roughened to cause them to properly grip or hold to the container and peel with which the device is used, and there is mounted on said jaw 15 a spring pawl or dog 16 designed to cooperate with the teeth of the ratchet 12, in order to hold sald jaw in a given position. Attached to this pawl is a hand crumed on the jaw 15, and so acted on by a coil or other spring 18, that it is normally pressed toward the ratchet 12.

Under conditions of operation a box of the construction illustrated at 19 in Fig. 4 is provided for the reception of'the bodies of dough, which are to be baked to form loaves of bread, and this box is of any desired or suitable length, being formed with the series of compartments 20 wherein the dough is placed to rise. After the dough has risen to the desired amount the box 19 is placed in my transferring machine with its opposite ends resting on the two jaws 10. The peel whose blade is as wide as the box is long, is then laid on top of the box in the position indicated at 21 and the sliding jaws 15 are lowered upon it by so operating the levers 17 thereof as to cause the pawls 16 to temporarily disengage the teeth of theratchets 12. When the two jaws have been placed in position to grip the box and peel, the levers are released whereupon the pawls 16, by engaging the ratchets, lock said jaws in such position. By means of the handles 9 the shafts 3 are then turned in their bearings 180 degrees, the power being transmitted through toothed segments 7 and 6, so that the box 19 is turned upside down and the bodies of dough therein are caused to be deposited upon the peel. By operating the levers 17 against the action of their springs 18 the pawls 16 are then withdrawn from the ratchets 12, whereupon the sliding jaws 15 with the peel and the bodies of dough thereon are allowed to slide downward on the bars 11 until stopped by the heads 13, the springs 1a acting to prevent undue jarring of the parts of the machine and the dough. The box 18 may now be removed from the peel and thereafter the latter with the bodies of dough is likewise removed, being taken to a suitable oven where the dough is discharged onto an elongated hearth. By moving the operatoperated lever 17, ful

v of said extension;

ing lever 9 in a direction opposite to that above noted the parts of the machine are restored tothe positions shown in Fig. 1 and are then ready to transfer the contents of another boX to a second. peel.

I claim:

l. The combination ina box inverting machine of a standard; a shaft rotatably mounted thereon; a jaw mounted on the shaft and having an extension at right angles thereto; a second jaw slidably mounted on said extension; means for holding said second jaw in any adjusted position; and a cushion spring for the latter jaw on the outer end 2. The combination in a boX inverting machine of a standard; a jaw structure rotatably mounted thereon and including a fixed jaw; an extension projecting at right angles tothe axis ofrotation of said structure; a ratchet on said extension; a second jaw slidably mounted on the extension; a pawl on said movable jaw; and a cushion spring for the movable jaw adjacent the end of the extension. I

3. The combination in a box inverting machine of a standard having a bearing' a substantially horizontal shaft mounted in the bearing; atright angles to the shaft; a head on the extension; acoiled spring on the extension in engagement with the head; a ratchet on the extension; a second jaw slidable on the extension toward and from the first jaw; a pawl carried by the second jaw in position to cooperate with the ratchet, with means a fixed jaw with an extension name to this specificatlon, 1n the for rotating the shaft and its associate parts through a predetermined angle at will.

4:. The combination in a box inverting machine of a standard having a'bearing; a shaft rotatably mounted in said bearing; a jaw mounted on said shaft; a guide projecting from the jaw at right" angles to the shaft; a rack on said guide; a second jaw movably mounted on the guide; a pawl carried by said jaw in position tocooperate with the rack; and an operating lever fulcrumed on the movable jaw and connected to said pawl.

5. The combination in a box inverting ma chine of a standard having a bearing; a shaft rotatably mounted in said bearing; a

jaw connected to said shaft; a guide bar forming an extension from said jaw and pro ecting at right angles to the shaft; a

series of teeth on said guide bar; a movable jaw slidable on the guide bar and ing with the first jaw; second jaw in position to cooperate with the teeth of the guide bar; with means on the second jaw operatively connected to the pawl for operating the same, said means consisting of a member projecting toward the line of the shaft from said pawl.

In testimony whereof, I have signed my presence of cooperattwo subscribing witnesses.
